[QUOTE="oexing, post: 178960, member: 1493"] You mean that transition point of my bit of straight milled face and the i.d. of 40mm ? That point is NOT the ignition point, you set 0.4 mm breaker gap - 15 thou - so the breaker heel will hit that obscure radius at some inclined spot anyway. It never goes down to the base /big i.d. of 42mm as this would be 1mm away and you only got 0.4mm gap. Hope this is some logic to follow ? So then after milling the proposed bit of flat you´d get a rubber polisher for the Dremel and put on a nice top rounding so no sharp edges will stay. Thisis not critical as no timing is made by that rounded edge. And anyway, there will be just some mild variation of curve between that new flat and the 40mm diameter, not harmful to the plastic heel. Vic [/QUOTE]
